3 Fig 2 Drawing demonstrates the locations of the 4 measurements of diameter and 6 measurements of length used in this study with reference to the abdominal aortic aneurysm. D1, aortic diameter at lowest renal; D2, maximal aneurysm diameter; D3, diameter at right iliac landing zone; D4, diameter at left iliac landing zone; L1, length of aortic neck below renals; L2, length of aorta from beginning of aneurysm to bifurcation; L3, length of aneurysmal right iliac; L4, length of nonaneurysmal right iliac; L5, length of aneurysmal left iliac; L6, length of nonaneurysmal left iliac.
